Which birds can imitate the sounds of a chainsaw, a gun shot, and a crying baby?

The Australian lyrebird has the most complex vocal organ of the passeriformes. This allows her to imitate the singing of any other bird and the calls of many animals, such as koalas or dingoes. In addition, there is ample evidence of masterful imitation of artificial sounds by lyrebirds: a chainsaw, an automobile engine and a horn, a shot from a gun, a crying child, and many others.

Which king changed the religion of the country in order to divorce his wife?

In order to marry Anne Boleyn, King Henry VIII of England had to divorce Catherine of Aragon, but the Pope did not allow this. Then the king submitted to Parliament for approval the Act of Restriction of Appeals. This act forbade all appeals to the Pope, proclaimed the Kingdom of England an empire, and endowed the emperor with absolute power. Another act a year later made Henry VIII the supreme head of the Church of England, essentially marking the beginning of its separation from Catholicism. Subsequently, England established its own form of Christianity, endowed with both Catholic and Reformation-Protestant attributes.

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Hydrogen is the cheapest way to cut emissions 03.09.2021

Green hydrogen produced using clean energy will be the cheapest way to reduce steel industry CO2 emissions to zero by 2050. This assessment was given by the research organization Bloomberg NEF.

The production of "green" steel using hydrogen currently provides for premiums on the price. By 2050, the cost of the process is likely to be less than production based on metallurgical coal or natural gas, despite the construction of new plants, according to Bloomberg NEF.

Geography will be one of the main factors in evaluating the most cost-effective ways to produce green steel. In particular, a country with high supply can make hydrogen the main fuel for steel production, while a country with developed hydroelectric power or other "clean" energy sources can electrify steelmaking using molten oxide electrolysis.

Other technologies that could contribute to the decarbonization of steel include carbon capture and storage technologies, alternative iron making processes, and carbon offsets.

"The cost of many of these technologies could come down due to economies of scale and greater efficiency," Bloomberg NEF stressed.

On the other hand, consulting firm McKinsey believes that steel production using hydrogen, carbon capture and storage technologies, carbon capture and use technologies can pay off no earlier than 2050. To do this, it is necessary to increase the scale of hydrogen production.
